I. What are the main factors affecting the quality of carbide tools?
By utilizing the high hardness of tungsten carbide and improving its toughness, a metallic binder is used to bond the tungsten carbide, enabling this material to possess hardness far superior to high-speed steel. Carbide tools offer a series of excellent properties, including high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. In particular, their high hardness and wear resistance remain largely unchanged even at 500°C and remain high at 1000°C.Factors influencing the characteristics and applications of carbide tools include:
1.Challenging workpiece materials,
such as alternative metals and difficult-to-machine alloys. Some of these materials have machinability less than 1/4 that of steel, and some can cost hundreds of dollars per pound.
2. Increasingly complex workpiece geometries
such as thin-walled workpieces and intricately shaped aerospace components.
3. Large-sized workpieces
particularly the growing demand for turbine and heavy machinery parts. The high per-unit cost of these workpieces places significant demands on carbide tool machining.
4. Increasingly specific quality and performance requirements,
such as demands for improved fatigue strength on the surface of machined parts.
Analysis of factors determining the quality of carbide tools:
(I) Hardness and Toughness
Carbide tools possess a unique advantage in balancing hardness and toughness. Tungsten carbide (WC) itself has very high hardness (exceeding that of corundum or aluminum oxide) and maintains this hardness even at elevated temperatures. However, it lacks sufficient toughness, which is essential for cutting tools. To leverage the high hardness of tungsten carbide while improving its toughness, a metallic binder is used to bond the tungsten carbide. This results in a material that not only far exceeds the hardness of high-speed steel but also withstands the cutting forces in most machining applications. Additionally, it can endure the high temperatures generated during high-speed machining. Therefore, the suitability of carbide tool performance for specific machining tasks largely depends on the initial powder manufacturing process.
(II) Powder Manufacturing Process for Carbide Tools
Tungsten carbide powder is produced by carburizing tungsten (W) powder. The characteristics of the tungsten carbide powder (especially its particle size) are primarily determined by the particle size of the raw tungsten powder and the temperature and duration of the carburization process. Chemical control is also critical, as the carbon content must remain constant (close to the theoretical stoichiometric ratio of 6.13% by weight). To control the powder particle size in subsequent processes, small amounts of vanadium and/or chromium may be added before carburization. Different process conditions and machining applications require specific combinations of tungsten carbide particle size, carbon content, vanadium content, and chromium content. Variations in these combinations can produce a wide range of tungsten carbide powders.
